In joining that band, he filled a spot previously occupied by his older brother Dean Paul Martin, who was killed in 1987 in a military plane crash.

Martin had spent recent years on tour, performing a tribute show to his legendary father. His dad became a cultural icon in the 1950s and '60s as a member of the famed Rat Pack, which also featured Frank Sinatra and Sammy Davis Jr., among others.

In 2002, seven years after his father's death, Martin published a book titled "That's Amore" about his life and growing up as a member of the famed musician's family.

In one memorable passage, Martin recalled his star-studded 21st birthday party that included appearances by John Lennon, David Bowie, Ringo Starr, Elizabeth Taylor and Elton John.

The performer, who was divorced, was one of Dean Martin's seven children. He is survived by his three daughters, his mother, four sisters and an older brother.
